Electron spin resonance driven photogalvanic effect in graphene-based structures
C. Bray, I. Yahniuk, L. E. Golub +13
We report an electron-spin-resonance-driven linear photogalvanic effect (LPGE) in unbiased monolayer graphene and WSe_2/graphene heterostructures. Under linearly polarized 45--75 G…
Terahertz field-driven nonlinear Hall effect and other second order transport phenomena in two-dimensional tellurene
M. D. Moldavskaya, L. E. Golub, E. Mönch +4
We study terahertz field-driven second-order nonlinear electron transport phenomena, including the nonlinear Hall effect (NLHE), in two-dimensional tellurene flakes. The dc current…
Positive Terahertz Photoconductivity in CdHgTe Under Hydrostatic Pressure
Ivan Yahniuk, Dmitriy A. Kozlov, Mariya D. Moldavskaya +10
Positive terahertz photoconductivity is observed at room temperature in CdHgTe thin films with different Cd contents. We show that electron gas heating caused by Drude-like absorpt…
Terahertz radiation driven nonlinear transport phenomena in two-dimensional tellurene
Erwin Mönch, Mariya D. Moldavskaya, Leonid E. Golub +7
Nonlinear electron transport induced by polarized terahertz radiation is studied in two-dimensional tellurene at room temperature. A direct current, quadratic in the radiation's el…
Testing the tomographic Fermi liquid hypothesis with high-order cyclotron resonance
Ilia Moiseenko, Erwin Mönch, Kirill Kapralov +3
Recent theoretical studies of carrier-carrier scattering in degenerate two-dimensional systems have revealed radically different relaxation times for odd and even angular harmonics…
Terahertz and gigahertz magneto-ratchets in graphene-based 2D metamaterials
Marcel Hild, Erwin Mönch, Leonid E. Golub +15
We report on the observation and study of the magneto-ratchet effect in a graphene-based two-dimensional metamaterial formed by a graphite gate that is placed below a graphene mono…
Nonlinear helicity anomalies in the cyclotron resonance photoresistance of two-dimensional electron systems
Erwin Mönch, Sophia Schweiss, Ivan Yahniuk +7
Our studies of the cyclotron resonance (CR) photoresistance in GaAs-based two-dimensional electron systems (2DES) reveal an anomalously low sensitivity to the helicity of the incom…
Cyclotron- and magnetoplasmon resonances in bilayer graphene ratchets
Erwin Mönch, Sergey O. Potashin, Katja Lindner +10
We report on a tunable - by magnetic field and gate voltage - conversion of terahertz radiation into a dc current in spatially modulated bilayer graphene. We experimentally demonst…
Highly superlinear photogalvanic effects in (BiSb)(TeSe): Probing 3D topological insulator surface states at room temperature
Sergey N. Danilov, Leonid E. Golub, Thomas Mayer +8
We report on the observation of complex nonlinear intensity dependence of the circular and linear photogalvanic currents induced by infrared radiation in compensated (BiSb$…
Spin polarisation by current
Sergey D. Ganichev, Maxim Trushin, John Schliemann
This is an overview of current-induced spin polarization in gyrotropic semiconductor nanostructures. Such a spin polarization as response to a charge current may be classified as t…
Helicity sensitive terahertz radiation detection by dual-grating-gate high electron mobility transistors
P. Faltermeier, P. Olbrich, W. Probst +5
We report on the observation of a radiation helicity sensitive photocurrent excited by terahertz (THz) radiation in dual-grating-gate (DGG) InAlAs/InGaAs/InAlAs/InP high electron m…
Interplay of Rashba/Dresselhaus spin splittings
S. D. Ganichev, L. E. Golub
The paper reviews the interplay of Rashba/Dresselhaus spin splittings in various two dimensional systems made of III-V, wurtzite and SiGe. We discuss the symmetry aspects of the li…
